Smartphones are awesome. Always having the Internet in the palm of your hand is fabulous, and being constantly connected to your peers and co-workers makes you super-productive, right?

If anything, your smartphone is a huge distraction that stands between you and actually getting work done. Before you can even think about sitting down and being productive, you’ll first need to play a few games, shoot off some emails, check you friends’ Facebook Timelines…and then the second you decide to start working, you’ll get 56 push notifications from Twitter, Instagram, and Clash of Clans.

Your smartphone definitely makes you less productive. Here’s why.

You’re always working

You might think that being able to fire off work emails in the middle of the night makes you extra productive, but you’re wrong. Being constantly connected to work makes you less productive during the work day; after all, if you don’t finish a task at the office, no worries, you can just do it on your phone later…

You can’t sleep

Science says that the bluish light from smartphone screens interferes with your ability to get a good night’s sleep. That’s right. Your phone actually makes you less productive…at sleeping.

Constant notifications

Are push notifications actually useful? Do you really need to know every single time someone likes one of your pictures on Facebook? Probably not. And those constant interruptions are probably not great for getting work done.

Email: The ultimate productivity-killer

Email is particularly bad for your productivity because it masquerades itself as work. Why not take a break and answer some emails? You’re still technically working! Add in a push notification every time you get a new email and…well…

You’re bad at remembering things

Did you know that Internet usage affects your memory? When you know that the answer to a question is just a Google search away, there’s no reason for you to remember what the answer actually is. And thanks to your smartphone, you have the Internet everywhere.

Freemium game addiction

You probably thought that freemium games that force you to wait between turns are perfect. After all, they can’t kill your productivity too much, since a hiatus is basically built in. Yeah, that would work if you played just one freemium game, but you play 15—and by the time you’re done with the 15th, the first one is ready to go again!

You’re actually a terrible multi-tasker

Trying to do many things at once doesn’t make you more efficient, it just makes you bad at all of those things. Driving and texting? Bad. Texting and working? Bad. Driving and working? Probably bad, unless you’re a truck driver.
